FED3
We are using FED3 devices to deliver food and quantify intake in the homecage
FED3 are devices were created by Lex Kravitz. If you want to buid one from scratch, here's the list of materials.
Luckily, you can get the electronics from Open Ephys Production site. Link here.
You can 3D print or order the prints. Check information here
On the heart of the FED3 devices, there's an Adafruit M0 board. This means you will be using the Arduino IDE for managing code and communicating with the device. Carefully follow the instructions on the hackaday page (link below).
You can find all the relevant information here
You can also find a Quick Guide and the code with explanation in GitHub.
Please check the videos for FED device on YouTube
You can use this tool for data analysis.
FED3 devices are powered by batteries that take quite a long time to refill. Although they last for a bit more than a week during operation, they can take up to 2 days to fully charge.
The current solution is to have extra batteries charged. It's a good idea to have extra battery packs charging with this charger. Just swap them on the device when they get low.
FED3 devices ship with a real time clock that needs to be set to a proper time.
To flash/upload sketches, put the Adalogger it into "bootloader" by doing a "double-clicking" on the little reset button on the board. When it is ready to accept code, the red LED on the Adalogger should "breathe" like this: https://www.youtube.com/watch?v=-Ce02eltnIw
In Ubuntu machine, try running Arduino IDE as sudo, so that there's no problem with permissions:
sudo arduino
NOTE: This means you cannot just double-click on .ino files, you have to always open them from an instance of the IDE that has been opened as sudo!
If you are using a Windows machine, some things might be easier. In general, most info out there is for Windows machines, but watch out, you might need other drivers depending on Windows 7 or Windows 10! Luckily I had a Windows machine available, so I:
Installed fresh arduino IDE 1.8 copied the libraries (following install guide on hackaday) Configured additional boards manager on Preferences (link to https://adafruit.github.io/arduino-board-index/package_adafruit_index.json) Installed Adafruit SAMD board 1.5.5 (following install guide on hackaday and recent issues) Java 8 (this machine didn't have Java and the first iteration returned a java error)
Uploaded the sketches with no problem. Clock updated, FED3 back to work. Your clock should be good to go until the next daylight savings time messes with your data or the clock's battery dies, whichever comes first!
Your questions will be probably answered if you visit these sites or contact these people.
